Apartment: Ben's place was fantastic for me as a solo traveler. It had all the necessary amenities and more. The place was well equipped with dishware, utensils, basic cooking ingredients (salt, oil, pepper, fish sauce, etc.), iron, washing machine, fridge, electric kettle, etc. As a late-riser, I really appreciated the dark curtains which blocked out the early morning sunlight really well. Best of all, it was super clean. The apartment complex itself has a lovely pool, a gym, and a convenience store.
Location: The apartment is located a very short walk (around 5 mins) from the BTS station (Silom line), and there was a mall nearby (around 10 mins walk) with a big grocery store, food court, a full department store, etc. Right opposite to The Mall, there was a local market with food stalls and groceries as well. It takes around 20 mins or so to get to the main the Siam Square area.
Communication: I greatly appreciated that Ben was super fast in responding to questions, and she provided excellent instructions (with step by step photos) on checking-in, turning on the hotplates in the apartment, and accessing common areas in the building (e.g., pool, gym, etc.).
